Hi,
My mum got me a LRP A2-STX 2.4GHz controller. I had problems with the first one that was replaced now I am having the same problem. I have binded the receiver & control, changed the batteries twice. The problem I am having is it stops responding, and makes my tyres/steering twitch left & right. When I steer it still only twitches about 2mm left/right.
Can anyone help me, my mum doesnt really want to take it back again. I think she thinks I am doing something wrong.
Thanks
